UTP Cable Specifications

For 1000BASE-T transmission, the cable must be:

Category 5 UTP or better

22-26 AWG, 100

@ 1MHz

EIA/TIA 568a or EIA/TIA 568b

Using UTP Category 5 Cable in Gigabit over Copper Installations

For Gigabit over copper installations, Category 5 UTP or better 1000BASE-T cable must
comply with the IEEE 802.3ab 1000BASE-T standard. For new installations, Category 5e
(enhanced Category 5) or better cable is recommended.

RJ-45 Pinouts and Crossover Function

The Ethernet standard also specifies that each segment implement a crossover function to
connect the transmitter of one device to the receiver of a device at the other end, and vice-
versa. The crossover function may be implemented internally at the hub or switch, or
externally through the twisted-pair media.
